Torque multiplication has essentially ceased and the torque converter is behaving in a manner similar to a simple fluid coupling. In modern automotive applications, it is usually at this stage of operation where the lock-up clutch is applied, a procedure that tends to improve fuel efficiency.
By historical context of comparison, the '50 Packard Ultramatic which was a torque converter applied two speed lock-up design with high and low range for four forward speeds and the '50 Studebaker/Detroit Gear featured a lock-up torque converter with three forward speeds. The lock-up feature of Packard's Ultramatic and Studebaker's DG 250 is ...
In an automatic transmission, the role of the clutch is performed by a torque converter. However, the transmission itself often includes internal clutches, such as a lock-up clutch to prevent slippage of the torque converter, in order to reduce the energy loss through the transmission and therefore improve fuel economy.

Once fully locked, the torque converter no longer applies torque multiplication and will spin at the same speed as the engine. This provides a major increase in fuel economy. Modern designs provide partial lockup in lower gears to improve fuel economy further, but this can increase wear on the clutch components.
The 5G-Tronic (model W5A 330 and W5A 580 · type 722.6) is an electronically shifted 5-speed overdrive automatic transmission with torque converter lock-up (typically in gears 3, 4 and 5) and 2-speed for reverse.
